C++学习

用于提高程序运行速度，缺点是会多占用内存

inline double square(double x)
{
	return x * x;
}
int main()
{
	double a, b;
	double c = 13.0;
	a = square(5.0);
	b = square(4.5 + 7.5);
	cout << "a = " << a << ", b = " << b << "n";
	cout << "c = " << c;
	cout << ", c squared = " << square(c++) << "n";
	cout << "Now c = " << c << "n";
	return 0;
}
